Balanced incomplete block designs useful for consumer experimentation

A Table of 127 balanced incomplete block design parameters is given intende d to be useful to those constructing presentation orders for consumer produ ct evaluation experiments. Designs that may have row-column balance or bloc k resolution are identified, since these are useful in overcoming bias intr oduced through presentation order effects or for constructing multi-session experiments, respectively. Only one partial experimental plan is given. In stead guidance is given on general construction methods by means of three e xamples. Plans for the designs may be obtained through reference to a widel y available work on combinatorial design or with a computer program availab le from the authors. (C) 2001 Elsevier Science Ltd.
